The Reds recruited Salah from the Serie A side a year ago with the Egyptian winger scoring only less goals than Barcelonaâ€™s Lionel Messi across Europe. Salah set a new Premier League record for the most goals in a 38-game season with 32.
His 44-goal haul across all competitions saw him rack up a number of individual accolades as he formed a formidable front-three alongside Sadio Mane and Roberto Firmino. That trio fired them to the Champions League final, even beating Roma 7-6 in the semi-finals along the way with Salah scoring twice in the first leg.
The forwardâ€™s first year at Liverpool makes the ÂŁ37.9million fee that they spent on the ex-Chelsea man appear a bargain – although itâ€™s easy to forget that it was widely questioned when he first moved to Merseyside.
Liverpool returned to Rome for another big signing this summer, splashing a then-world record fee on a keeper of ÂŁ65m – ÂŁ56m guaranteed with a further ÂŁ9m in add-ons – on goalkeeper Alisson last month.
Jurgen Klopp had long been linked with a move for the Brazilian shot-stopper but had been put off by Romaâ€™s price demands.
It was suspected that the Giallorossi wanted to make up for losing money on Salah, who would have commanded a bigger fee had the deal gone through later in the summer after the game-changing ÂŁ198m transfer of Neymar to Paris Saint-Germain.
Pallotta called Salah an â€śunbelievable bargainâ€ť in hindsight back in April, bemoaning that he only had one year left on his contract and that UEFA were monitoring the club over the Financial Fair Play rules – backing Roma a corner.
But with Loris Karius under increasing pressure at Anfield and Alisson having expressed his desire to move to England, Liverpool and Roma eventually agreed a deal which has now seen Kloppâ€™s charges strongly tipped as Premier League title contenders as a result.
And in a Q&A interview with Roma players Kostas Manolas and Justin Kluivert on the clubâ€™s official YouTube channel, Pallotta opened up on the difficulty of losing Salah and Alisson.
Asked who was the hardest player to lose, the American businessman said: â€ťI liked Salah a lot.Â
â€śUnbeknownst to a lot of people, or a lot of people donâ€™t seem to know, is that we didnâ€™t have a choice in him leaving.Â
â€śIt was difficult. He had one year left and he asked to leave and he felt like he had something to prove back in the Premier League.
“It was difficult for that. I think Alissonâ€™s not an easy one. People outside think you have choices and a lot of the time you donâ€™t so you just try to make the best of it.Â
â€śItâ€™s not an easy thing – thereâ€™s a lot of thought that goes into that kind of stuff and a lot of the time, youâ€™ve just got no choice.â€ť
Salahâ€™s sensational first season saw him pen a new five-year contract with Liverpool last month, improving his wages to ÂŁ200,000-a-week to make him the clubâ€™s top earner.
He will hope to start where he left off or Liverpool when they play their first match of the new Premier League season against West Ham at Anfield this Sunday (1.30pm) – with Alisson also scheduled to make his competitive debut for the club against the Hammers.
